A high-performance natural fibre ingredient for concrete ($66 billion market size) - with structural testing and commercial use cases validated.

  • A natural fibre ingredient engineered for concrete - developed with cement manufacturers and construction companies

  • Concrete producers lack scalable, drop-in, carbon-negative reinforcement materials; demand driven by regulation, embodied carbon limits, and procurement mandates

  • Unlike traditional additives, it delivers reinforcement at lower material density, reduced concrete mass and transport cost, and permanent carbon storage within the structure

  • Industrial production of 500+ tonnes across multiple European sites over 5 years

Low-Density Structural Reinforcement

Why We Win

  • Built with the buyers: Developed inside a working group of 30+ global construction leaders - ensuring direct alignment with procurement, performance, and integration requirements from day one.

  • Carbon-negative at material level: Hemp fibre sequesters CO₂ during growth and retains it in concrete - independently verified via Life Cycle Assessment, enabling net-negative material substitution.

  • Approved and entering use: First commercial use-cases approved, with a live 2026 demonstration site generating real-world performance data for scaled adoption.

  • Supply that can scale: Delivered via Rare Earth OS (with European production active and expansion across APAC and the Americas already in motion) and industrial scale demand for protein reducing cost base.

Our cutting-edge innovation was selected by CapitaLand in their global innovation shortlist and ranked as a top 5 sustainable construction solution (out of 1,478 startups and scaleups).

FAQs

  • Our ingredient was developed alongside industry partners seeking lower-carbon ingredients without compromising scalability or commercial viability. We compete on pricing, performance and rely on zero adaptation to existing on site deployment or concrete mixing machinery.

  • We are price competitive and there is no green premium. We price based solely on performance and fit within the pricing parameters of established ingredients used today.

  • We are advancing commercial deployment through initial industrial-scale use cases while expanding into additional concrete applications and markets. Our strategy focuses on working within existing regulatory and construction frameworks to accelerate adoption.

  • A standardised Life Cycle Assessment (LCA) was carried out according to ISO guidelines (ISO, 2006a, ISO, 2006b) covering the protein and fibre; from first seed planted to final use.

  • Yes. Hemp is one of the fastest-scaling industrial crops available, with the ability to produce food, materials and energy from a single harvest in approximately 100 days. Through our supply chain partnerships and operating system, we are focused on scaling reliable industrial supply globally.

  • Our approach is designed to integrate into existing production and distribution systems with minimal operational disruption. By working with established industry partners, we enable adoption without requiring major infrastructure changes or new manufacturing processes.
